3. Click Universal Access.

Controlling screen brightness in your Power Options

After adjusting your laptop's brightness, it should retain the new settings automatically. If the brightness settings are not retained after a computer restart, they are probably being overridden by settings in the Power Options menu. If this is the case, you'll need to create a custom power plan, which can be done by accessing the Power Options utility in the Control Panel.

Driver issues

If the key combination method is not working and you've made the appropriate adjustments in Power Options, it is likely your computer has a video driver problem. Driver issues usually occur after updating the video drivers. Monitor drivers can also cause this problem. To resolve any potential monitor related issues, reinstall the monitor by following the steps below.

1. Click the + or arrow next to Monitors to expand the list.
2. Highlight any detected monitors under Monitors and press delete to remove them from the computer.
3. Once the monitors are removed from Device Manager, under Action, click Scan for Hardware changes to let Windows re-detect the monitor and install the applicable drivers.

Finally, we also recommend downloading the latest video drivers directly from the video card manufacturer. If this problem was caused because you updated the drivers, install an earlier version of the video drivers to see if that resolves the issue.

Laptop brightness is still not enough or screen is black

If, after following the steps above your brightness is still not enough, plug your laptop into the wall. If the laptop is plugged in but still is not bright enough, try the suggestions on the page linked below.
